Wordpress LScache Plugin: Failed to post via WordPress: hash does not match: ClientCB
Last Updated on: Wed, 15 Apr 2026 00:00:02 My site is always experiencing an error when accessing the image optimization tab in litespeed cache, see this screenshot: http://prntscr.com/pyb2vw What can it be? Report number: GTZSFUGD Hi @felipetto, Please follow https://www.litespeedtech.com/support/wiki/doku.php/litespeed_wiki:cache:lscwp:image-optimization#server_list to add whitelist, after that, try to Clean Up Unfinished Data > Reset IAPI Key > Send Optimization Data to see does it work? the problem was in the plugin https://www.wordpress.org/plugins/duracelltomi-google-tag-manager/ I had to keep it off to perform the image optimization process. Thanks for the update, we will improve the image optm function in v3, please check with the plugin again to see does it fix.
